Water Cooler Not Dispensing Cold Water: Why it Happens and How to Fix It

A water cooler is a convenient device to have around your home, office or any establishment for that matter. It gives everyone immediate access to potable and refreshing water to keep them hydrated all day. But after a few years of regular wear and tear, you might notice that your water cooler stopped dispensing cold water. Or in some cases, the water it dispensed was not as cold as they used to. When this happens, we’re here to tell you that there’s no need to panic. This is a common issue among water coolers, and there are varying solutions depending on the main problem. If we know how does a water dispenser work, we can easily fix why the water cooler stopped dispensing cold water.

Here, we will talk about the reasons why water coolers stop dispersing cold water and give you solutions to fix that.

Why It Happens

Before we dabble into the ways you can make your cooler dispense cold water again, here are some of the reasons that might be causing this issue.


This is one of the most obvious reasons why your water cooler isn’t working properly. Bear in mind that these coolers run on electric power to function properly, so it’s only natural that it has to be plugged in to produce cold water. Otherwise, you simply have a fancy tap water faucet.

While this may seem like a plain reason, you’d be surprised by the number of people who actually forget to plug in their coolers. Maybe they’re too busy or preoccupied with tasks at hand, and they just forget to plug the cooler altogether. This is especially common in offices and other busy work areas.

Exceeding Demand

Another common reason why your water cooler may not be dispensing cold water properly is due to the exceeding demand for cold water.

Water coolers do not produce unlimited cold water 24/7. They have limited chill rates, and this is something that’s often overlooked.

For example, a water cooler that has a chill rate of 8 gallons per hour wouldn’t be able to work efficiently if people using it drink around 10 gallons per hour. In contrast, the same water cooler will be able to provide everyone with cold water if they only require 8 or fewer gallons of water per hour.

Thermostat Set High

In some cases, you may have set the thermostat to a high temperature.

Some of today’s water coolers have adjustable thermostats that allow you to control the temperature that you want to maintain for your water. These little knobs are easily accessible, so switching temperatures won’t be a problem.

There are instances when you may have wanted warm water at first, but you forgot to switch the thermostat back to a low temperature. Or, you may have had guests who accidentally set the thermostat high.

Thus, we recommend checking on your thermostat first. If your problem doesn’t seem to fall under these first three scenarios, then your water cooler may have a problem with your Freon levels – or any other internal issue.

It Needs A Reset

Sometimes, you have to remind yourself that your water cooler is also an electronic device. As such, it is susceptible to glitches from time to time – but not something that a simple reset could fix.

Freon Needs Refill

The Freon inside your water cooler is the cooling agent responsible for turning regular water to cold water. It is a chemical that helps absorb heat while also cooling down the water in its reservoir.

However, the Freon levels on your cooler will deplete over time. When this happens, you will notice that your cooler may not be as efficient with cooling water as it once was.

Some newer designs give you easy access to determine whether your Freon needs a refill or not. And this comes in handy so you wouldn’t have to disassemble your cooler just to check.

Other Internal Issues

If none of these situations seem to match your problem, then there may be something wrong with your unit. Perhaps there’s a hardware issue or some of its wirings were cut or damaged.

How to Fix Your Water Cooler

Now that you know all the possible reasons why your water cooler isn’t dispensing cold water, here are the ways for you to address each issue.


Obviously, the solution to an unplugged water cooler is to have it plugged to the nearest power source. While this may be simple enough for standalone units, the process may be trickier in the case of wall-mounted models with internal power receptacles.

After plugging it in, we suggest waiting for a few minutes before testing it out. If the water still isn’t cold, then you can proceed with trying out all the other solutions below.

Exceeding Demand

Another easy solution that we can recommend is to wait for a few minutes after the previous user has dispensed water. Not only will this prevent exceeding demands from the water cooler, but this will also help keep the water reservoir remain filled with cold water.

Thermostat Set High

In case you notice that your thermostat is set at a high temperature, then the easiest way is to set it down to your preferred water temperature.

It Needs a Reset

If none of the previous solutions seem to work, then you could try resetting your water cooler.

To do so, simply drain all the water from your cooler’s reservoir. This will depend on what unit you’re using, so we recommend checking its instruction manual for more detailed instructions on how to drain your cooler’s water reservoir.

After draining the reservoir, turn the cooler off and disconnect it from your power source. Leave it unplugged for an entire day before plugging it back in.

After a day, you can now plug the cooler to its respective power source and switch it back on. Wait for a few hours to allow the water to be chilled – around 5 hours would do. After the lapse of this time, you can now enjoy your cold water.

Freon Needs Refill

If the reset still doesn’t do the trick, then there must be something wrong with your Freon levels. For this solution, we recommend getting a professional to make the Freon refills for you.

Bear in mind that Freon is a chemical – and while it is considered as non-toxic, you need to be a certified professional before you can work on the refills.

Other Internal Issues

If none of these solutions seem to work, then there might be internal issues that require immediate action. In this case, we recommend having a professional look into your water cooler for a more precise diagnosis.

But before hiring a professional, you should also check if it still covered by the warranty. Doing so will help you save a lot of money in case of manufacturing defects, or in case of faulty parts.
